Stress leads to more heart attacks among police, firefighters
Police officers and firefighters are far more likely than the general population to suffer heart attacks or sudden cardiac death on the job. But their coronary CT calcium scores don't differ all that much from those of the general population, according to a study presented at the American College of Cardiology meeting in Atlanta.

Organ-based tube-current modulation cuts breast dose
VIENNA - Radiation doses to the breast can be cut by nearly 40% using a new organ-based dose modulation technique in combination with a noise-optimized image reconstruction method. The two techniques must be used together if the resulting images are to remain readable, researchers reported.

CT doses, widely variable in Europe, are reduced by staff efforts
VIENNA - Although dose variations remain wide on the continent, there are opportunities for substantial improvement with dose-reduction training and programs, according to two European studies of clinical CT doses presented back-to-back Saturday at the European Congress of Radiology.

Coronary CTA predicts long-term outcomes
VIENNA - A decade's worth of coronary CT angiography (CTA) studies is starting to reveal the modality's long-term predictive powers, if a study from one of Poland's largest heart centers is any indication.

High pitch equals low dose in coronary CT angiography
VIENNA - High-pitch dual-source CT exams can evaluate the coronary arteries using about a third of the dose of even prospectively triggered exams, according to a study presented in Thursday's cardiac sessions of the European Congress of Radiology.

320-row CT minimizes dose in pediatric abdominal studies
It's no secret that CT radiation dose levels in children -- especially in the emergency department, where patients are fidgety and physicians need fast answers -- are too high. One solution, investigated by researchers from Toronto and Berlin, is wide-area-detector scans with 320-detector-row CT.

Images depict biopsy-confirmed prostate cancer in a 56-year-old man. (A) Pretreatment axial T2-weighted fast spin-echo MRI scan and (B) apparent diffusion coefficient map acquired with a 3T scanner show the tumor in the left transition zone (arrows). (C) Intraoperative 1.5-T MRI scan shows the contoured rectal wall (red line), prostate margin (blue outline), and region of interest (orange outline). (D) Intraoperative MRI scan shows a focused ultrasound beam path (blue) overlaid on the treatment plan. The rectangular boxes show each sonication spot. (E) Thermal map obtained during treatment shows heat deposition color-coded in red and overlaid on the sonication spot. (F) Axial gadobutrol-enhanced MRI scan obtained immediately after treatment shows the devascularized ablated volume (arrows). (G) Corresponding T2-weighted fast spin-echo 3T MRI scan obtained at 24 months after ablation shows fibrosis and volume loss in the left transition zone (arrows). Findings from a biopsy showed scar tissue, negative for malignancy at the treatment site.

A 60-year-old male patient with clinical suspicion of lung cancer. PET/CT scan showed FDG-avid pulmonary nodules in the upper lobe of the left lung (red arrow), with a size of 2.2 × 1.3 cm, SUVmax of 12.2, Ki-65 min of 0.016 ml/g/min, and Ki-30 min of 0.014 ml/g/min. Surgical pathology confirmed a granulomatous lesion. In addition, PET/CT scan showed many FDG-avid lung nodules in the mediastinum. (A, static PET maximum intensity projection; B, static PET SUV image; C, static PET/CT fusion image; D, dynamic PET Ki-65 min image; E, dynamic PET Ki-30 min image). Image courtesy of EJNMMI Physics.
